Although institutional investors have a preference for large capitalization stocks, over time they have shifted their preferences toward smaller, riskier securities. These changes in aggregate preferences have arisen primarily from changes in the preferences of each class of institution, rather than changes in the importance of different classes. Evidence also suggests that recent growth in institutional investment combined with this shift in preferences helps explain why markets in general, and smaller stocks in particular, have exhibited greater firm-specific risk and liquidity in recent years. Additional analyses suggest that institutional investors moved toward smaller securities because such securities offer "greener pastures."

According to the Diamond-Verrecchia hypothesis, if increases in short interest are correlated with information that is not yet public, they should precipitate a price adjustment. Stocks with unexpected increases in short interest are found to generate statistically significant, but small, negative abnormal returns for a short period around the announcement date. When the sample is divided into stocks with and without tradable options, nonoptioned stocks closely mimic these results but the optioned stocks do not. In a cross-sectional analysis of individual firms, the short-term negative abnormal returns are found to be 1) more negative, the higher the degree of unexpected short interest and, 2) less negative if the firm has tradable options.

ABSTRACT This paper employs a new approach to study the effects of option trading on the behavior of underlying stock prices. Extant research compares distributional properties of the stock price at two points in time divided by an event in the option market that might affect price behavior. As an alternative, we examine the stock price adjustment to the release of quarterly earnings using samples of firms with and without listed options. We find the two samples exhibit different adjustment processes, with the nonoption firms requiring substantially more time to adjust.

We examine the high volume return premium across 41 different countries and find it to be a phenomenon found in both developed and emerging markets. The premium is not caused by systematic differences in risk or liquidity. Using Merton's (1987) investor recognition hypothesis as a guide, we find the magnitude of the premium is generally associated with country and firm characteristics hypothesized to affect returns subsequent to a change in a stock's visibility. We also characterize the time-series properties of the premium and consider economic trading strategies.

This article examines potential explanations for the wealth effects surrounding dividend change announcements. We find that new information concerning managers' investment policies is not revealed at the time of the dividend announcement. We also find that dividend increases (decreases) are associated with subsequent significant increases (decreases) in capital expenditures over the three years following the dividend change, and that dividend change announcements are associated with revisions in analysts' forecasts of current earnings. These results are consistent with the cash flow signaling hypothesis rather than the free cash flow hypothesis as an explanation for the observed stock price reactions to dividend change announcements.

The authors test the hypothesis that, when their compensation is linked to relative performance, managers of investment portfolios likely to end up as 'losers' will manipulate fund risk differently than those managing portfolios likely to be 'winners.' An empirical investigation of the performance of 334 growth-oriented mutual funds during 1976 to 1991 demonstrates that mid-year losers tend to increase fund volatility in the latter part of an annual assessment period to a greater extent than mid-year winners. Furthermore, the authors show that this effect became stronger as industry growth and investor awareness of fund performance increased over time.

We document that backfilling in the ExecuComp database introduces a data-conditioning bias that can affect inferences and make replicating previous work difficult. Although backfilling can be advantageous due to greater data coverage, if not addressed, the oversampling of firms with strong managerial incentives and higher subsequent returns leads to a significant upward bias in abnormal compensation, pay-for-performance sensitivity, and the magnitudes of several previously established relations. The bias also can lead to one misinterpreting the appropriate functional form of a relation and whether the data support one compensation theory over another. We offer methods to address this issue.

Abstract Hedge fund activists have ambiguous relationships with the institutional shareholders in their target firms. While some support their activities, others counter their actions. Due to their relatively small holdings in target firms, activists typically need the cooperation of other institutional shareholders that are willing to influence the activists’ campaign success. We find the presence of “activism-friendly” institutions as owners is associated with an increased probability of being a target, higher long-term stock returns, and higher operating performance. Overall, we provide evidence suggesting the composition of a firm’s ownership has significant effects on hedge fund activists’ decisions and outcomes.
